The following are specific examples of the m A further object is to provide a cocoa-sugar process which. however. should be considered as compound in which the sugar phase consists of typical and illustrative and not as limiting the both dextrose and sucrose and which compound invention to the details specified: is hard enough to grind properly.

The product will have a mosture content of 3% to 5%. At this moisture-content and with the amount of tri-calcium phosphate added any tendency of the powder to cake in the containers is counteracted.

The product compounded as just described will have the following composition, approximately, dry basis but including water of crystallization:

This analysis is to be regarded merelyas typical and illustrative and not as limiting the invention to the particular proportions given,

Example 2.-In case a compound richer in cocoa and-equivalent in sweetness to the product of Example 1 is required, sucrose may be substituted in, part for -dextrose; but in that case in order to obtain a compound hard enough to grind properly, one sugar m-ust predominate over the-other to the extent represented by weight percentages of substantially 75 to 25,. That is,

the sugars to the sugar must consist either of 75% sucrose or more or 75% dextrose or more. If a high percentage of cocoa is required and, atthe same time, considerable sweetness, the batch may consist- (in addition to the lecithin, tri-calcium phosphate and flavoring extracts) of cocoa, 16.25% dextrose and 48.75% cane -sugar., If less sweetness or a smaller amount of cocoa in the compound is desired, the sugars may be in proportions of dextrose or more and 25% sucrose or less.

. The intention is to cover theinvention as broadly. as the state of the art warrants within the scope of the appendedvclaims.

I claim: 1. Powdered chocolate-sugar compound in which the sugar element consists of dextrose and sucrose with one such 'sugarpredominating to the I extent of substantially at least 75%.

2. Process of making a dry powdered chocolate and sugar compound which consists in mixing the chocolate with 'water and with sucrose and dextrose, one of which sugars is present in at least three times the quantity of .the other; allowing :crystalliz'e; and then hardening and grinding the-crystallized product.

- 3. Powdered chocolate-sugar compound in which the sugar element consists of substantially 75% dextrose and 25% sucrose.

4. Powdered" chocolate-sugar compound in which the sugar element consists of substantially 75% sucrose'and 25% dextrose. 1
